Discussion on the geological characteristics and development strategies of the oil reservoir in Ka 6 well area

This paper takes the Ka 6 well area of the Kaindike oilfield as the research object. In response to the unclear distribution of oil sand bodies and remaining oil in the area, as well as the low development efficiency, a comprehensive study of reservoir geological characteristics and development strategies is systematically conducted by utilizing core, logging, seismic, and production performance data. It is clarified that the study area develops three sets of oil reservoirs: the Jurassic Qigu Formation, the Paleogene Ziniquanzi Formation, and the Anjihaihe Formation. The reservoirs are primarily characterized by low porosity and low permeability, with lithologies mostly being glutenite and medium-coarse sandstone. The reservoir types are mainly tectonically controlled lithological reservoirs and lithology-controlled lenticular lithological reservoirs. Through dynamic data analysis, it is determined that the inter-well connectivity is poor. Combined with the analysis of remaining oil potential, targeted suggestions for layer perforation, fracturing, and new well deployment are proposed. Additionally, the well pattern and comprehensive management plan are optimized, providing technical support for efficient development in the well area.
